I'm not 100% sure but my best guess would be a rectangle. ( do not give brainliest if wrong, i wanna make sure its right)
Correct answer:
26 = -13x
X = -2
if you need a false answer, make up any number!
In the second one I'm pretty sure you just measure the length of the points.
The answer is 45 because 45-15=30, therefore x=45.
I really don’t know the answer I’m sorry
